- Insomnia is a major health problem and is associated with low quality of life, high absenteeism from work, and physical and mental illness

- Patients report that sleep is too short, too interrupted or of poor quality, or a combination of these

- It is important to exclude other sleep disorders as a cause of insomnia: referral to a specialist sleep centre for more assessment may be necessary in cases in which the presentation is unusual or the diagnosis is in doubt

- Overall management approaches aim to acknowledge distress, treat the primary cause, educate the patient about trigger factors, and establish good sleep habits

- Current drug treatments for insomnia are hypnotic agents that affect the gamma-aminobutyric acid (GABA)-A-benzodiazepine receptor

- Several new compounds are currently in development
